VSC7156XYT-03 Description

Short technical summary and product information.

The VSC7156XYT-03 is an enhanced 24-PHY Serial Attached SCSI (SAS) edge/fanout expander from Analog Devices / Maxim Integrated. It supports both 1.5Gbps and 3.0Gbps SAS speeds, as defined by ANSI T10 specifications.

This device is targeted at embedded applications in midrange and enterprise storage environments, including blade servers, JBODs, and RAID systems. It offers an upgrade path for systems currently using parallel SCSI technology. The VSC7156XYT-03 provides active port expansion for up to 24 connected PHYs through a high-performance internal non-blocking cross-bar matrix.

Key features include programmable output preemphasis and input signal equalization for consistent signal quality. The on-board v3000 CPU acts as an SMP management client, participating in enclosure management functions via serial I²C interfaces, an embedded Ethernet controller, or vendor-specific SMP implementations. The expander contains all necessary functions for implementing a 1.5Gbps or 3.0Gbps SAS enterprise server or JBOD system, distributing SAS signals to disk drives.

This product is noted as 'Not Recommended for New Designs' and some versions may be subject to Last Time Buy. It is typically used in distributing SAS signals to an array of disk drives in servers or external enclosures.
